A Broadband, Low-Noise Time-Domain System for EMI Measurements through Ka-Band up to 40 GHz

1307 F4 coverIn this article, a time-domain EMI measurement system for the frequency range from 10 Hz to 40 GHz is presented. Signals with a frequency of up to 1.1 GHz are sampled by an ultra-fast floating-point analog-to-digital-converter (ADC) and processed in real-time on a field-programmable-gatearray (FPGA). An ultra-broadband multi-stage down-converter allows for the measurement of signals with frequencies up to 40 GHz. Measurement times can be reduced by several orders of magnitude compared to traditional EMI-receivers that work in frequency-domain.

IQD Announces New Low Phase Noise and Low Power Clock Oscillator

IQD Frequency Products has introduced a new crystal clock oscillator offering two key features – low phase noise and low current consumption. The CFPS-115 is available at any frequency between 26 to 44 MHz and offers a standard 45/55% duty cycle HCMOS output.
